Leachates from cementitious grouting materials used for reducing water inflow are hyperalkaline and chemically reactive with the engineered barriers and host rock for geological disposal of high-level radioactive waste. Evaluation methods for long-term alteration of the fractured rock have been developed since the extent of chemical modification may influence the transport and retardation properties of radionuclides in the far field. The present study shows the current status of the development of the methodology (i.e., procedure, models, and simulation codes) for evaluating the effects of cementitious grouting materials on groundwater and rock.
